"I need you to open your ears and close your mouth," Kamenetz said to the crowd of about two dozen.

Many were holding black and yellow signs calling on the county to retract their plan to build on the school on the site of Mays Chapel Park.

The groundbreaking was part of a news conference being held.

"What's really sad here is that we have adults who act like children it really is disgraceful," yelled to the crowd.

"You're disgraceful," a member of the crowd shouted back at Kamenetz.

"Show some class!" Kamenetz shouted back.

Kamenetz later told reporters the school will serve about 700 students and added that the county owns the land.

"I was still hoping they wouldn't take it, but I guess we are not strong enough to fight against them," said Solang Deavux, a Mays Chapel resident.

The group has fought the school in the past, but have lost their battle.

"It's a nice piece of property, and I think that it's really going to cause quite a commotion in the area with the amount of traffic and the flow," said Claire Sunday, who lives near the site.

The multi-million dollar building will also feature a walking path around the school.

The school is scheduled to open near the end of 2014.

After the news conference Don Mohler, the county executive's chief of staff released a statement, which said: "The county executive got angry. He saw people screaming and shouting. He didn't think that was a good example for the children who were excited about getting a new school. He saw the children getting upset and he reacted as parent."
